Flat and Solid Shapes

Mathematicians in Room 117 have been hard at work learning about 3 dimensional (solid) shapes.  We been describing them, composing them, and comparing them to 2 dimensional (flat) shapes.

All of us have had so much fun with all of the hands on activities!  We stared off this unit with an introductory shapes lesson with Mrs. Murphy's class.

We love the 3D shape song by Teacher Tipster!  Click here to watch the video and sing along!

After learning about which solid shapes can roll, stack, and slide, we used play doh to create these 3 dimensional shapes and reinforce our new math vocabulary of faces, edges, and corners.

 During math workshop, students rotated through three stations to strengthen their skills of sorting 3D shapes, composing shapes and pictures with 2D shapes, and identifying 3D shapes within pictures.

I think the favorite activity was the building station!  Students had to use their imagination and construct with our 3 dimensional foam shapes and then record the shapes they used.

We are becoming quite the shape experts!

What shapes can you spot in your house or while you are outside for a walk on a beautiful, sunny day?

CCSS.Math.Content.K.G.A.2
Correctly name shapes regardless of their orientations or overall size.
CCSS.Math.Content.K.G.A.3
Identify shapes as two-dimensional (lying in a plane, "flat") or three-dimensional ("solid").
CCSS.Math.Content.K.G.B.4
Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/"corners") and other attributes (e.g., having sides of equal length).
CCSS.Math.Content.K.G.B.5
Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.
